Daniel,

Should this be backported to 4.8?


Yes, I would consider this a candidate for backporting.

FWIW, Daniel's email is bouncing. Anshul, do you want to test/confirm?

I believe this is fixed now; my email server was changed while I was gone
for the holiday and apparently the change was not tested properly.

Please backport the patch to stable-4.8. I have tested it.

Anshul
